What doesn't scale is developers who only care about their tiny
sliver of Linux and don't stick their heads up from time to time and
look around.  This is an opportunity for people to become more involved
in the development of Linux as a whole, instead of just worrying about
their bit.  You're not "a Xen developer".  You're a Linux developer
whose current focus is on Xen.
